Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a dispensing closure, a container for fluid having an outlet opening, an axially perforated cork fitting into the Opening, a metal cap having a circumferential wall secured to the container about the outlet opening and having a perforation in registry with the cork perforation, an annular boss on the cap adjacent to and around the perforation on the side toward the cork, a second annular boss on the cap circumferentially adjacent the wall on the same side as the first and radial stiffening ribs joining the bosses.

2. In a dispensing closure, a container for fluid having an outlet opening, an axially perforated cork fitting into the opening, a metal cap having a circumferential wall secured to the container about the outlet opening, and'having a perforation in regis try with the cork perforation, an annular boss on the cap adjacent to and around the perforation, facing the top of the cork, a second annular boss circumferentially adjacent the wall and engaging the top of the container about the outlet and spaced radial stiffening ribs joining the bosses.

3. In a dispensing closure, a container for fluid having an outlet opening, an axially perforated cork fitting into the opening, a metal cap having a circumferential wall embracing the outlet and having a perforation in registry with the cork perforation, two spaced annular bosses on the cap, one sealing against the top of the cork, and the other engaging the container about the outlet and circumferentially spaced radial stiffening ribs joining the bosses.

4. In a dispensing closure, a container for fluid having an outlet opening and a rim free from threads and about the opening, a metal flange having a skirt adapted to engage with the rim to hold the flange to the bottle and a boss within the flange engaging the bottle about the opening.

5. In a dispensing closure, a container for fluid having an outlet opening and a rim about the opening, a metal flange having a skirt adapted to engage with the rim to hold the flange to the bottle and a boss and inwardly extending ribs engaging the end face of the bottle about the opening.

6. In a dispensing closure, a container for fluid having an outlet opening and a rim about the opening, a flange having a skirt engaging with the rim and having two spaced interior annular bosses and a pouring outlet, and a cork engaged by one of the bosses to seal against leakage of liquid between the skirt and the rim.

7. In a dispensing closure, a container for fluid having an outlet opening and a rim about the opening, a metal flange having a skirt for engagement about the rim, an interior boss in line with the rim and an outlet pouring spout in combination with a cork lying between the boss and the rim engaging the boss to seal against leakage between the rim and skirt.

8. In a dispensing bottle a closure cap adapted to fit about an outer bottle flange against the end of the bottle and beneath the flange and having an annulus to engage the end of the bottle, an apertured boss forming a pouring spout and stiffening ribs extending between the boss and annulus.
